“…Some studies have shown that the degradation of CSD produced acidic degradable products and formed a local acidic microenvironment, which caused inflammatory reaction in vivo. 18,19 In this study, the pH of the solution decreased from 7.40 to 6.86 after the CSD cement immersion into PBS for 12 weeks, indicating that some acidic degradable products emerged during soaking. However, the pH of the solution for 20 nl-MSC slightly increased from 7.40 to 7.45, indicating that some basic products emerged after the degradation of nl-MS, which might neutralize the acidic degradable products of CSD.…”

Nanoporous lithium doping magnesium silicate (nl-MS) was introduced into calcium sulfate hemihydrate to prepare calcium sulfate composite (nl-MSC) bone cements. The introduction of nl-MS improved the in vitro degradability of nl-MSC cements, which could neutralize acidic degradable products of calcium sulfate and prevented the pH from dropping. The cements were implanted into the bone defects of femur bone of rabbits, and the results of histological and immunohistochemical analysis revealed that massive new bone tissue formed in the defects while the cements were degradable, indicating that the osteogenesis and degradability of the nl-MSC cements were much better than the control calcium sulfate dihydrate (CSD) cements. Furthermore, the positive expression of vascular endothelial growth factor and collagen type I for nl-MSC cements was higher than CSD, indicating that addition of nl-MS into the cements enhanced vascularization and osteogenic differentiation. The results suggested that the nl-MSC cements with good biocompatibility and degradability could promote vascularization and osteogenesis, and had great potential to treat bone defects.

The formation of biofilm is one of the main contributing factors for unsuccessful treatment of osteomyelitis. It is formed through bacterial adhesion to the fragments of dead bone. Poor perfusion or devascularization of an infected bone with changes in local pH further limits the diffusion of parenteral antibiotics.Calcium Sulfate , a biocompatible and completely absorbable local carrier for antibiotics, has shown promising results in treating osteomyelitis. It is associated with less systemic effects and compliance issues when compared with conventional treatment of surgical debridement and prolonged systemic antibiotics.
